In search of lost genes

It is well known that genes are passed from one generation to the next. In addition, new genes arise regularly, although the number of genes in a particular organism does not seem to increase. The paradox has been solved ...

New look inside cell nucleus could improve cancer diagnostics

Researchers have successfully isolated and sequenced the entire messenger RNA – the "genetic photocopies" – contained in the nucleus of a single brain cell. This research, published in the journal Proceedings of the National ...

"Kissing genes" breakthrough

In a ground-breaking discovery that will have a major impact on our understanding of the function of DNA, our genetic blueprint, a group of scientists from Wits and the Council for Scientific and Industrial Research (CSIR) ...

Cell nuclei harbor factories that transcribe genes

Our genetic heritage is contained—and protected—in the nucleus of the cells that compose us. Copies of the DNA exit the nucleus to be read and translated into proteins in the cell cytoplasm. The transit between the nucleus ...

Secrets of pineapple nutrition revealed

(Phys.org) —A researcher from The University of Queensland, has conducted the world's first pineapple microarray to gain a better understanding of tropical fruit development at the molecular level.

RNA molecule behind behavior changes cued by environment

Quick changes in behavior – in worms, at least – can be triggered by a unique form of the molecule RNA acting within the nucleus of a cell, UC San Francisco researchers have discovered.
